I admit, I’m a bit of a fan of the Oracle Database Appliance. And I also admit there are some characteristics of the X5-2 ODA’s which made it sometimes a bit hard to fit in the needs of the customer. I’ll come to that later in this post. With the […]

The second and final post about an issue with a RAC-configuration with two SAN's. Problem was a i/o-freeze of minutes when crashing one of the two SAN's. The first post I ended with a 'cliffhanger' because we had a solution, but not tested it yet.

With this setup we are facing the issue that if we loose a complete SAN, the IO’s to the ASM diskgroups will be blocked for approx 3 till 4 minutes. Oracle does not like this. After 70 seconds after a freeze, rdbms is starting to reboot (expected behaviour).

This is the second post of my little project of building my own RAC on my Windows7-desktop (64-bits, 8GB RAM), using 3 VM’s (VM-workstation , 7.1.3 build-324285) :
* 2 VM’s for two RAC-nodes, based on OEL 5.5, 11.2.0.2 for infra, and database.
* 1 VM as my own SAN, based on Openfiler 2.3 (free), for ASM.

My current job doesn’t offer me at the moment the opportunity to play with RAC or other stuff, so I decided to build my own RAC on my Windows7-desktop (64-bits, 8GB RAM), using 3 VM’s (VM-workstation , 7.1.3 build-324285) :
* 2 VM’s for two RAC-nodes, based on OEL 5.5, 11.2.0.2 for infra, and database.
* 1 VM as my own SAN, based on Openfiler 2.3, for ASM.

While installing a grid - infrastructure on my own RAC-cluster (VMware), using ASM with Openfiler as by own SAN, the prerequisite-check fails at step 15 with :
PRVF-5150 : Path ORCL:VOL1 is not a valid path on all nodes

While building my own RAC on two VM's, using a third VM with Openfiler on it as my SAN, I had to dowload, install, configure and load ASMLIB. Loading didn't seem to go smoothly at my own project. First I analyzed what I did, steps I took
